Design and Application of a Fully Rotatable Non-contact Electrical Connector
Magnetic couplers are the most important components in underwater wireless energy transmission (UWPT) systems.Their configuration determines their application scenarios,and design and optimization of their parameters di-rectly affect overall output power and efficiency of the system.This paper proposes the design of a new fully rotatable non-contact electrical connector for underwater unmanned vehicles.In addition to axial rotation,the ball head and ball seat can also achieve radial rotation,making the entire system convenient and reliable,operating safely,and flexible in motion. The proposed electrical connector was integrated into the prototype of the UWPT system for verification,achieving wire-less energy transmission at radial offset angles of 0°to 45°,and maintaining a total system efficiency of over 85%.
